I am trying to replace the water pump on my 98 Tahoe. Anyone have any suggestions as to how to get the fan off? I tried increasing the tension on the belt to hold it, but it still slips (for those that don't know, 96 and later fans thread directly onto the water pump shaft, the four bolts through the pulley no longer hold the fan on. ) When I did the water pump in my pickup, I think we just used the friction of the belt to hold it. Also, how do I reset the radio since I disconnected the battery?
